BY CHARLES OWEN WATERHOUSE. PRINTED BY LONDON: ORDER OF THE TRUSTEES. 1879. PRINTED BY TAYLOR AND FRANCIS,, RED LION COURT, FLEET STREET.. * PREFACE, v THIS series (of which the present is the first part) has the same object and scope as the series of 'Illustrations of Typical Specimens of Lepidoptera Heterocera,' viz. to give illustrations, accompanied by diagnoses or short descriptions, of those specimens of Coleoptera in the British Museum from which species have been described in other works, or are described now for the first time. The several parts will be devoted as much as possible td species belonging to the same Family or the same Fauna. ",, The descriptions of this first part have been prepared by Mr. C. O. Waterhouse, one of the Senior Assistants in the Department of Zoology. ALBERT GUNTHER, Keeper of the Department of Zoology. British Museum, November 22, 1879. 295470 I SYSTEMATIC INIDEX, LYCIDAE.

Niger, opacus; thorace coccineo, lateribus reflexis, angulis posticis acutis; scutello nigro; elytris basi thorace baud latioribus, postice gradatim ampliatis, coccineis, quadricostatis, costis parum elevatis, interstitiis subtiliter punctulatis. Long. 10 lin. Hab. Allahabad (J. C. Bowringq, Esq.). Antennae three quarters the length of the elytra, compressed, rather broad, strongly dentate. Thorax a little broader than long, in the middle in front rather angular, constricted a little behind the middle, the posterior angles diverging; the anterior and lateral margins broadly reflexed, with a short carina in front, and a carina B 2 LYCIDIE. on each side at the constriction; disk with a longitudinal mesial impression. Scutellum narrowed towards the apex. Elytra long, much enlarged posteriorly; each elytron with four costae, the interstices finely and thickly punctured, and with indications of reticulation here and there. CALOCHROMUS. Gudrin, Ann.

Closely allied to C. scutellaris, Er., but relatively broader; thorax broader, with a deep mesial impression, broader in the middle; there is a deep round fovea at the anterior angle, and a deep impression within the posterior angle, the part between the anterior fovea and the posterior impression raised, so that the impressions are not confluent as in scutellaris. The antennae are broader than in scutellaris, in which the fourth joint is twice as long as broad, whereas in basalis it is not more than one third longer than broad. Section II. Maxillary palpi less compactly jointed, the apical joint not globular. Calochromus melanurus. (Plate I. fig. 5.) Waterh., Cistula Ent., ii. 1877, p. 196.

Thorax very delicately and closely punctured, scarcely pubescent; disk with a fine mesial line, more deeply impressed behind, there is also a deep impression at each anterior angle; the posterior angles are rather inflated, and within them there is a deep impression. The elytra are rusty yellow, dull, and pubescent, bluish black at the apex. CALOCHROMUS. 3 Calochromus orbatus. (Plate I. fig. 3.) Waterh., Cistula Ent., ii. 1877, p. 197. Statura omnino pra3cedentis, differt tamen antennarum articulo tertio longiori; elytris totis ferrugineis. Long. 5-6k lin. Hab. Philippine Is. and Darjeeling. This species only differs from C. melanurus in having the elytra uniform rusty yellow, and in having the third joint of the antennae nearly three times as long as its greatest width, whereas in C. melanurus it is at most twice as long as broad. Calochromus apicalis. (Plate I. fig. 10.) Omalysus apicalis, Hope, Gray's Zool. Miscel., 1831, p. 24. Niger; elytris rufis, plaga magna basali nigra; thorace transverso, medio canaliculato, utrinque biimpresso, angulis rotundatis; elytris thorace paulo latioribus, postice parum ampliatis, apico rotundatis, pubescentibus. d. Long. 6 lin., lat. 21 lin. Hab. Nepal. A rather broad species. Antennae rather stout, half the length of the body; fourth joint as long as the two previous joints taken together, the fifth a little shorter; the sixth to ninth very slightly increasing in length, very little compressed, truncate at their apex. Thorax a quarter broader than long, moderately shining, the anterior angles are more rounded than the posterior; the central impressed line reaches from the posterior to the anterior margins, is well defined and of equal depth throughout; on each side are two large deep impressions, separated from each other by an oblique ridge. The elytra are at the base a little broader than the thorax, a little wider posteriorly, red, with a black (or bluish black) patch extending from the base to the posterior two thirds, leaving the margins and the apex red; each elytron has five impressed lines, the interstices narrow and slightly convex. The penultimate segment of the abdomen has a trapezoidal emargination at the apex. Calochromus aemulus. (Plate I. fig. 11.) Waterh., Cistula Ent., ii. 1877, p. 198. Niger, subopacus; thorace medio canaliculato, utrinque biimpresso; elytris dimidio basali ferrugineo-flavo, singulis tricostatis. Long. 31-4n lin. Hab. Sarawak (Wallace). Head convex, shining, rather closely and excessively finely punc2 4 LYCIDIE. tured; rostrum very short, strongly transverse; at the base of each antenna there is a slight round tumour; mandibles pitchy. Thorax shining, clothed with very delicate grey pubescence, only visible in some lights. Elytra densely pubescent; each elytron with three distinct roof-like costae, and with an indication of a fourth. c. Antennae nearly as long as the elytra; third joint a little elongate, very obliquely truncate at the apex; fourth joint as long as the two preceding taken together, compressed, broader than the third; the fifth to tenth the same length as the third, the eighth, ninth, and tenth diminishing in width, the fifth to eighth with the lower anterior angle a little produced, the eleventh joint a little longer and much narrower than the preceding. Thorax subquadrate, rather straight at the sides, arched in front, with a deep mesial longitudinal channel, and on each side two deep fovese, the raised portion dividing the foveae oblique. Penultimate segment of the abdomen triangularly emarginate at the apex, and with a deep longitudinal mesial channel.?. Antennae two thirds the length of the elytra; third joint as broad, at its apex as long, fourth to ninth scarcely longer than broad, the tenth a little narrower, eleventh narrowed at the apex. Thorax a little broader than long, rather narrowed in front. The rest as in the male. Calochromus rugatus. (Plate I. fig. 4.) Waterh., Cistula Ent., ii. 1877, p. 199. Elongatus, niger; elytris piceo-testaceis, dense rubro-sericeis, striis impressis, interstitiis convexiusculis, secundo et quarto fere costatis. c. Long. 5k lin. Hab. Allahabad (J. C. Bowring, Esq.). Head gently convex, impressed on the forehead; rostrum extremely short, the space between the antennal pit and the base of the mandible about half the diameter of the antennal pit. Antennae about two thirds the length of the elytra and (for the genus) rather slender; the sixth to tenth joints slightly diminishing in length and a trifle more slender; eleventh joint a little longer, parallel, scarcely acuminate at the apex. Thorax black, margined, delicately pubescent; disk transversely impressed behind the middle, deeply impressed in front of and behind the oblique lateral ridge. Penultimate segment of the abdomen with a deep incision. Calochromus ruber. (Plate I. fig. 6.) Water., Cistula Ent., ii. 1877, p. 199. Elongatus, niger, supra piceo-testaceus, dense rubro-sericeus; CALOCHROMUS. 5 thorace medio longitudinaliter canaliculato, lateribus bifoveatis; elytris minus elongatis unicoloribus, obsolete bicostatis.. Long. 53 lin. Hab. Allahabad (J. C. Bowring, Esq.). Antennee compressed; the third joint as long as the two preceding together; fourth a little longer, truncate at the apex; fifth to ninth nearly the same form, but gradually more obliquely truncate at the apex, so that the lower anterior angle becomes more acute but is not produced; the tenth joint is rather smaller, very obliquely truncate; the eleventh narrow, parallel, acuminate at the apex. This species is very close to C. rugatus, but the lateral oblique ridge of the thorax is placed more posteriorly, and the lateral impressions are not so well defined; the space between the antennal pit and the base of the mandible is also much greater. Calochromus velutinus. (Plate I. fig. 7.) Waterh., Cistula Ent., ii. 1877, p. 199. Elongatus, piceo-niger, supra piceo-testaceus, dense fiavo-rufosericeus; thorace sat transverse, medio canaliculato, utrinque fortiter impresso; elytris obsolete bicostatis; abdomine cyaneo-nigro. Long. 5k lin. Hab. Burmah (J. C. Bowring, Esq.). Rather shorter and broader than C. ruber, the thorax more transverse, and with the ridge which divides the lateral impressions much more directed forwards; rostrum almost none, i. e., the space between the antennal pit and the base of the mandible is less than half the diameter of the pit, whilst in C. rzuber this space is quite equal to the diameter of the antennal pit. The third joint of the antennae is as long as the first, as long as its greatest width, obliquely truncate at the apex; the fourth joint as long as the two preceding together, a little longer than broad, very little narrowed at the base, straight at the apex; the fifth to tenth about the same length as the fourth, but gradually diminishing in width, scarcely oblique at the apex, their lower anterior angle a little less than a right angle; the eleventh joint much narrower, longer, parallel, acuminate at the apex. The thorax one sixth broader than long, a little narrower in front; disk convex, with a rather fine mesial channel; the sides deeply impressed, the usual oblique ridge very much directed forwards, almost parallel with the lateral margin. Elytra very gradually and very little enlarged posteriorly; each elytron with two narrow slightly raised coste, with an indication of a third. Calochromus segregatus. (Plate I. fig. 8.) Depressus, cyaneo-niger; thorace elytrisque ochraceo-rufis; 6 LYCIDA. thorace sat depresso latitudine paulo breviori, medio linea tenui impresso; elytris striis plurimis. i. Long. 4k lin. Hab. Java (J. C. Bowring, Esq.). Most nearly allied to C. velutinus, but more depressed. Thorax above less uneven, the mesial line finer, the sides rather straighter; the lateral ridge is less strong, a little more posterior, and very short. Scutellum red at the apex. Elytra nearly parallel, flat; each elytron with about seven finely impressed lines, the interstices flat; the extreme apex is bordered with black. Calochromus tarsalis. (Plate I. fig. 9.) Niger, parallelus; thorace transversim quadrato, lateribus rufis, baud marginatis; elytris rufis haud striatis; pedibus tenuibus, tarsis longis gracilibus. Long. 34 lin. Hab. India. General form and appearance of Lygistopterus sanguineus, but a little narrower. Rostrum none. Antennae slender. Thorax a little broader than long, straight at the sides, which are red, the disk with a fine mesial line; the lateral margins not incrassated; a slight swelling near the posterior angle indicates the usual lateral plica. Elytra as in L. sanguineus, but with no visible stria. Calochromus vestitus. (Plate II. fig. 2.) Waterh., Cistula Ent., ii. 1877, p. 200. Elongatus, postice paulo ampliatus, niger, vix cyanescens; thorace nigro (vel rubro), tenuissime rubro-sericeo; elytris rufo-testaceis, dense rufo-sericeis, costatis, apice nigro. d. Long. 3-4 lin.. Long. 5-6 lin. Hab. Penang (J. C. Bowring, Esq.).. Antennae about two thirds the length of the elytra, moderately broad in the middle, tapering to the apex. Rostrum extremely short, the space between the antennal pit and the base of the mandible about one third the diameter of the antennal pit. Thorax black, clothed with very fine silky-red pubescence, only visible in certain lights; the discoidal channel rather deep, the lateral impressions deep and well-defined. Scutellum black. Elytra clothed with bright red pubescence; each elytron with two not very prominent costae. The underside and the legs black, scarcely tinged with blue. Penultimate segment of the abdomen emarginate. S. Antennae rather shorter and broader than in the male. Rostrum a little more prominent; the space between the antennal pit and the base of the mandible about half the diameter of the pit. CALOCHROMUS. 7 Thorax reddish yellow, with the sides and the mesial line black. Each elytron with three distinct costae, the apex broadly black. Var. $. Thorax entirely red, the pubescence more dense. Elytra bicostate, the costa narrower. Calochromns lepidus. (Plate II. fig. 3.) Waterh., Cistula Ent., ii. 1877, p. 201. Cseruleus, nitidus; thorace vix brevissime pubescente; disco longitudinaliter fortiter impresso, lateribus biimpressis; elytris piceotestaceis. dense fulvo-rufo-pubescentibus, striis vix perspicue impressis, apice anguste nigro; antennis pedibusque violaceis. Long. -41 lin. Hab. Java (c ), Penang ( ) (J. C. Bowring, Esq.). A more slender species than any of the preceding, and rendered distinct by the beautiful shining blue thorax and violet antennae. The anterior angles of the thorax are much deflexed, and consequently do not show the margin so distinctly; the disk has not a fine mesial line, but a deep longitudinal impression; the lateral fossa are deep, but the oblique ridge which divides them is not so well defined as in most of the species. c. Antennae rather slender. Elytra with scarcely any trace of costse. Penultimate segment of the abdomen with a deep incision. S. Antennae very slightly dilated. Thorax more narrowed in front. Elytra bicostate. The two examples in the collection are from different localities, but there is no doubt that they should be associated as sexes of the same species. Calochromus longipennis. (Plate II. fig. 4.) Waterh., Cistula Ent., ii. 1877, p. 201. Elongatus, subparallelus, niger; thorace supra piceo, dense rufopubescente, medio foveola lanceolata impresso, lateribus biimpressis; scutello piceo, rufo-pubescente; elytris longissimis, dense rufopubescentibus, ad apicem nigris, costatis, costis angustioribus.. Long. 6; lin., lat. 154 lin. Hab. Sumatra (E. C. Buxton, Esq.). Forehead evenly convex, black, very finely pubescent, rostrum about three times as broad as long; maxillary palpi very stout. Antenne three quarters the length of the elytra, compressed; the third joint about twice as long as broad, emarginate at the apex; the fourth to ninth joints about equal in length, the lower anterior angle obliquely and much produced, increasingly so as they approach 8 LYCID/E. the apex; the tenth joint very oblique, a little smaller than the ninth, the eleventh compressed, fusiform. Thorax a little broader than long, somewhat narrowed in front, all the angles distinct but obtuse, with bright red pubescence; the disk convex, with a deep lanceolate fovea nearly reaching from the anterior to the posterior margins. Elytra very long, with bright red pubescence; each elytron with three not very distinct narrow costse, the outer one very obsolete. There can be no doubt that Micronychus bimaculatus, Motsch. (Bull. Mosc., 1861, i. p. 138), from Ceylon, is closely allied to 0. longipennis. It differs from it in having the forehead clothed with bright red pubescence, the thorax is much longer, the anterior angles are more deflexed, and the lateral fold is not so near the posterior angles. The British-Museum example has the elytra uniform bright red, the costae are not so prominent as in C. longipennis. Section III. Intermediate coxos of the male with a strong spine; base of the femur with a strong tooth; tibiae curved. Calochromus dispar. (Plate II. fig. 1.) Waterh., Cistula Ent., ii. 1877, p. 202. Cyaneo-niger, sat nitidus; elongatus, parum convexus; thorace marginato, medio canaliculato, utrinque biimpresso; elytris rufis, dense pubescentibus, postice paulo ampliatis. 6. Long. 6 lin. Hab. Borneo (J. Russell). This species has somewhat the appearance of C. orbatus, but has the elytra more ample posteriorly, less bluntly rounded at the apex, and the thorax is margined all round. The antennae are nearly as long as the elytra, not very approximate at their base. Clypeus gently emarginate. Intermediate coxse with a strong acute spine; the femur with a strong tooth near the base; the intermediate and posterior tibiae strongly curved. The penultimate segment of the abdomen is deeply notched in the middle. DEMOSIS. Lycus (genus 4), Waterh., Trans. Ent. Soc., 1878, p. 97. Antennae short, compact, dentate, of equal width throughout; the third joint a trife longer than broad, the fourth to tenth joints transverse. Rostrum distinct but short. Thorax rather transverse, quadrangular; the disk smooth, the margins reflexed. Elytra flattened, subparallel, with moderately distinct costae, the intervals punctured. LIPERNES. 9 Demosis peltatus. (Plate II. fig. 5.) Parallelus, depressus, piceo-niger; thoracis limbo elytrisque flavis, his apice nigris; abdominis marginibus late flavis. Long. 31 lin. HaT. Lake N'Gami (Andersson). Nearly parallel, the elytra very little wider than the thorax. Head and the basal joints of the antennae very slightly pitchy. Thorax nearly one third broader than long, yellow, shining and black in the middle; the sides subparallel, reflexed, the posterior angles very slightly prominent. Elytra very finely pubescent, widest rather before the middle; each elytron with four obtuse costse, the third abbreviated, the fourth continued over the shoulder, the intervals rugulose and obscurely punctured, the apical third black. At the time my account of the genera of Lycidce was written (Trans. Ent. Soc., 1878) this species was considered to be the Lycus serobicollis of Fghraeus, and is the species referred to under " Genus 4 " at p. 97. I have, however, since seen a different species named L. scrobicollis, one which in some respects agrees better with F&hraeus's description. It seems best therefore to consider the insect from Lake N'Gami a new species. LIPERNES. Characters of Lycostomus, but with the palpi short and thick; the apical joint of the maxillary palpi nearly as broad as long, convex, nearly straight on the outer side, rounded on the inner side. Thorax with a mesial impressed line, the margins thickened and narrowly reflexed. Each elytron with four costse, the fourth not elevated at the shoulder. Lipernes perspectus. (Plate II. fig. 11.) Niger, nitidus; thorace medio longitudinaliter impresso, marginibus anguste reflexis, angulis posticis acutis; elytris thorace paulo latioribus, subparallelis, testaceo-rufis, rugulosis, circa scutellum anguste nigro-cinctis.. Long. 5-6k lin., lat. 24-2i lin. Hab. Shanghai (Fortune). Rostrum short, about as long as broad; apical joint of the maxillary palpi very thick and ovate. Antennee moderately long and slender. Thorax rather small, scarcely narrowed in front; the mesial longitudinal channel is wider in the middle. One example has the extreme margins of the thorax rusty red. *'.;: 10 LYCIDME. LYCOSTOMUS.

Nepal (Gen. Hardwicke), Allahabad and Siam (J. C. Bowring, Esq.), Ceylon (Dr. Thwaites), Bootan (Dr. Pemberton). This species is very close to L. ferrugineus, F., but is relatively a little shorter, and the elytra are less parallel, more ample posteriorly and more evidently arcuate at the sides. The antennae are distinctly more slender. The thorax varies immensely in form, but is generally narrower in the d than in the?; the disk is black, frequently traversed by a fine mesial red line. The elytra are entirely deep red; a single example only has a short blackish stripe on the second interstice. L. ferrugineus, F. (Ent. Syst. Suppl., p. 125), with which the present species is above compared, will very probably prove to be a variety of Lycus marginatus, Fabr. (Syst. El., ii. p. 110). L. melanurus, Blanch. (Voy. Pole Sud, iv. p. 74, t. 6. f. 2), and L. bivittatus, Kirsch (Mittheil. aus. d. k. zool. Museum zu Dresden, 1875, i. p. 34), are evidently synonymous with marginatus. Lycostomus aqualis.

Closely allied to similis, Hope, but much more parallel in form. Antennae a little less slender than in that species. Rostrum a little shorter, and thicker at the base. Thorax broad, blackish in the middle. Elytra subparallel, red, the costse nearly parallel; at the posterior two thirds, the fourth costa is not further distant from the margin than it is from the third costa, the margin itself is more. thickened. i.

Near L. siinilis, Hope, but the teguments are more delicate, the colour flesh-colour, and the thorax has the sides less reflexed. Rostrum reddish testaceous, a little longer than broad. Antenne rather shorter than in similis and less broad. Thorax with the sides moderately reflexed, the posterior angles prominent and acute, the disk somewhat infuscated. Scutellum black, parallel at the sides, truncate at the apex. Elytra gradually but not much enlarged posteriorly, the sides rather straight, only arcuate near the apex; the third costa is somewhat indistinct, the fourth is strong, and forms a strong well-marked carina over the shoulder, more elevated than in similis. Lycostomus modestus. (Plate II. fig. 10.) Niger, opacus; thoracis lateribus elytrisque ferrugineo-rufis, regione scutellari anguste infuscato. Long. 6 lin., lat. 21 lin. Hab. Bootan (Pemberton), India (Boys). Opaque above. Rostrum a little longer than its width at the base, narrowed towards the apex. Antennae narrow and linear. Thorax trapeziform; the disk flat, dull black; the sides reflexed, red. Elytra dull red, slightly wider at the apex; each elytron with four equidistant costse; the interstices with rough transverse reticulation; the first, second, third, and fourth interstices with an indication of an interrupted intermediate costa. &'. Antennme a little more than half the length of the elytra, rather slender, all the joints elongate. i.

Rostrum moderate, about a quarter longer than its width at the base. Antennae rather slender, about half the length of the elytra. Thorax with the margins moderately reflexed, dull red, the 12 LYCIDA. disk llackish, the anterior and posterior margins narrowly bordered with red, the posterior angles acute. Scutellum black. Elytra dull red, gradually widening to near the apex; each elytron with four costee, the intervals roughly punctured, but with no distinct reticulation. Margins of the abdominal segments dull brick-red. $. Rostrum long and slender. Antennae a trifle shorter than in the male. Thorax very broad, the margins broadly reflexed and expanded, the sides rectilinear, the posterior angles a little less than right angles, the disk more or less blackish. Elytra dull red. Abdomen dull brick-red, blackish in the middle at the base. The two specimens above described as sexes are very dissimilar, but they have so much in common, besides the peculiar rusty-red colour, that there is little doubt that they should be associated as sexes. Lycostomus singularis. (Plate II. fig. 9.) Niger, opacus; thoracis lateribus elytrisque ferrugineo-rufis.. Long. 6| lin., lat. 2Q lin. Hab. South India (Walhouse). Very close to L. modestus, but differs in having no black on the elytra near the scutellum, and the sculpture of the elytra is much finer and without reticulation. Lycostomus rufiventris.

Scutellum red. Elytra somewhat parallel, rather pale red. Coxae and abdomen reddish. With the specimens above described are associated two other examples, which have the rostrum black, but do not differ materially in any other respect, and may therefore safely be considered varieties.

Long. 4-1-7 lin., lat. 21-33 lin. ilab. Ceylon (Dr. Thwaites); N. Bengal (Lieut. Campbell); Dacca (J. C. Bowring, Esq.). This species is very close to L. internexus, but has the teguments rather more delicate, the colour is paler; it is usually of a broader form, and the elytra are more ample, the sides posteriorly being more strongly arcuate. The antennue have the first three joints usually pale, but some examples have as many as seven pale joints. 6.Legs black, with the base of the femora pale. Si.Legs yellowish, with the tarsi and sometimes the apex of the tibiae black. Mr. Walker's type of L. divisus is merely a small example of his L. planicornis; both are females. Lycostomus nigripes. (Plate III. fig. 6.) Pyrochroa nigripes,.7abr., Mant. Ins., i. p. 163. Rufo-testaceus; antennis articulis 4t`-llum, femorum apice, tibias tarsisque nigris; thorace triangulari, sericeo-pubescenti; elytris postice sat ampliatis. Long. 5-k lin., hat. 21 lin. Hab. Siam (Banks); Penang (J. C. Bowring, Esq.). 14 LYCIDAE. Pinkish-testaceous. Rostrum a little longer than its width at the base. Thorax in the form of an equilateral triangle, the sides moderately reflexed. Elytra widened a little below the shoulders, rather ample before the apex, the sides rather strongly arcuate. Legs black, except the base of the femora.?. The foregoing description is taken from the original type in the Banksian collection. The specimen is said to come from Siam. There are three specimens in the British-Museum collection from Penang which agree very nearly with the Fabrician type, but the colour is more yellow, the thorax less regularly triangular, and the sides are not so suddenly reflexed. The male example is entirely pale below, with the apex of the posterior tibiae and the tarsi fuscous, and the apex of the elytra is black; the two females have the elytra entirely yellow, the metasternum and abdomen are more or less dusky, and the legs are blackish, with the base of the femora pale. Lycostomus placidus. (Plate III. fig. 7.) Ochraceus; antennarum articulis 4tO-llum, palpis, tibiis tarsisque nigris. Long. 4-7 lin., lat. 1~-31 lin. Far. 1. Femoribus apice nigris. c, $. Var. 2. Elytris apice nigris. d, 9. Hab. Hong Kong (J. C. Bowring, Esq.). Pale ochreous. The eyes, the fourth to the eleventh joints of the antennae, the tibiae, and tarsi black. Thorax narrowed in front, the disk somewhat shining. Elytra not much enlarged towards the apex, the sides rather straight, the humeral ridge not very strong. This species differs from L. nigripes in being longer in the elytra, which are also a little more parallel. The thorax varies immensely, but appears to be always relatively longer than in L. nigripes, and the disk is more shining. The legs are generally black, except at the base of the femora, but a small example has the femora almost entirely yellow. The specimens which have the apex of the elytra black are the largest specimens, and have the thorax broader than in those with unicolorous elytra; but the largest unicolorous specimen and the smallest example with black apex to the elytra agree so nearly in size and form that I cannot consider them distinct species. The specimens appear nearly all to have been taken together, and are marked by Mr. Bowring 2517150. The variety with the black apex to the elytra much resembles some specimens of L. analis, but may be distinguished by the relatively longer elytra (which are not so much arcuate at the sides), and by the form of the thorax, which is less trapeziform and less silky than in analis. LYCOSTOMUS. 15 Lycostomus angustatus. (Plate III. fig. 9.) Piceo-fuscus, elongatus, angustus; thorace elytrisque sordide flavis, illo medio plus minusve infuscato. Long. 41-5 lin., lat. 1 -2 lin. Hab. Java (J. C. Bowring, Esq.). Distinct from all its allies by its elongate narrow form. Rostrum yellowish, a little longer than broad. Antennae half the length of the elytra, slender, fuscous, the basal joint a little paler. Thorax elongate trapeziform, much narrower in front; the disk a little fuscous; the sides narrowly reflexed, rectilinear; the posterior angles very acute. Scutellum fuscous. Elytra very long, narrow at the base, moderately enlarged posteriorly; the sides rectilinear for two thirds their length, then gently arcuate. Legs fuscous, the coxre paler. Abdomen shining, pitchy.

Differs only from the female of L. foliaceus in having the black at the apex of the elytra straight in front.

Old Calabar. Not unlike the female of L. foliaceus, but the disk of the thorax is black, and the posterior angles are more acute. The elytra are roughly punctured and are less parallel, the second costa is very LYOUS. 19 acute and prominent, and the shoulders are laterally expanded, the base of the fourth costa forming the edge of this expansion.

Extremely close to L. latiSSiMUs, and only to be distinguished by the black at the apex of the elytra, the inner margin of which is parallel to the line of the side and is not suffused at the apex.

Sometimes there is only a black lateral spot, and an apical border parallel with the margin as in L. elegans, but generally the black at the apex is suffused. Sometimes the lateral spot is more or less united with the black at the apex; it is so slightly in the type specimen ( S ) of L. latissimus, in the Linnean collection. The variety L. harpago, Th., has the two lateral spots united by a fascia. Variety fenestratus, Murray, has this fascia and the black at the apex confluent. Sometimes the elytra are entirely black except a yellow fascia. The extent to which the elytra are dilated in the male and the form of the apical truncature appear to vary considerably, while the various systems of coloration above mentioned are not constantly accompanied by any one form of elytra. With regard to the synonymy given above, it must be noticed that Fabricius does not mention the black in the middle of the thorax, for which reason Guerin (Rev. Zool., 1847, p. 227) provisionally renamed the Fabrician insect Fcbricii. There can, however, be little doubt that the omission was an oversight on the part of Fabricius, especially as the examples in the Banksian collection (said to have been named by Fabricius) are typical latissimus, the male example having the lateral spot on the elytra partly united with the black at the apex as in the Linnean type. The description given by Olivier applies well to latissimus, Linn.; but his figure (Ent., ii. 29, t. 1. f. 2) represents quite a distinct species allied to L. ampliatus, FMhr., and is almost certainly the male of the species which he names L. proboscideus* (Ent., ii. 29, p. 8, t. 1. f. 6). BROXYUTS. Rostrum none. Apical joint of palpi very large, long, knifeshaped. Antennwe very compressed, simple. Thorax with an interrupted mesial carina. Elytra very ample, inflated, quadricostate, the interstices divided into subquadrate spaces by transverse carine. The species upon which this genus is founded closely resembles Galopteron dilatatum, Bourgeois, but differs in the form of the palpi. * This species as well as ferrugineus, Fab., lateralis, Dalm., and perhaps some other Fabrician species of Lycus, appear to be omitted from Gemminger and v. Harold's Catalogue of Coleoptera. UALOPTER~ON. 2 21 Broxylus pfeiffer,%. (Plate Y. fig. 8.) Calopteron? pfeilfieri, Waterk., Trans. Ent. Soc., 1878, p. 106.

"1New Hebrides " (J. C7. Bowring, Esq.). The thorax is moderately narrowed in front, with a complete well-defined nmesial carina, the posterior angles acute. Elytra at the base not wider than the thorax, gradually but not much wider posteriorly, the three spots on each elytron are rather pale dusky. Since this species was originally described I have come to the conclusion that it is only a variety of the American Calopteron tricolor, Oliv.; in which case the locality with which it is marked must be an error. 0. tricolor usually has the tibiae dusky, which is not the case in the specimen described as notatum; but the species is very variable. Calopteron typioum. (Plate VI. fig. 1.) Digrapba typica, JAewm., Entomol. Mag., 1838, v. p. 380. Var. D. discrepans, Newm., 1. c. p. 381. Atrum; thoracis lateribus elytrorumque basi et fascia' mediana' flavis. Long. 6-8 Uin. flab. North America. 22 LYCIDB. Thorax one third broader than long, yellow, with a rather broad black stripe in the middle; the posterior angles acute, but not much diverging. Elytra yellow, with the apical third black, and with a black band at one third from the base; each elytron has four costse, the interstices with rather close transverse costse. The middle of the sternum frequently yellow. Variety.-The variety named discrepans by Newman differs from the above in having the black of the fascia ascending at the suture and surrounding the scutellum. The posterior angles of the thorax in the type specimen are slightly diverging. Calopteron dorsale. (Plate VI. fig. 2.) Digrapha dorsalis, Newm., Entom. Mag., 1838, v. p. 381. Nigrum; thorace lateribus flavis; elytris nervis quatuor elevatis, interstitiis reticulatis, flavis, fascia ante medium ad marginem abbreviata apiceque late cyaneo-nigris. Long. 5k lin. Hab. East Florida. The yellow at the sides of the thorax varies; in the type specimen it is very narrow, but in another it is broad. The elytra are slightly gibbous at the anterior fascia, and distinctly so in the apical region. Calopteron divisum. (Plate VI. fig. 3.) Digrapha divisa, Newm., Entom. Mag., 1838, v. p. 381. Nigrum; thorace lateribus elytrisque flavis, his apice late cyaneonigris. Long. 5-9 lin. Hab. North America. Very close to C. dorsale; but besides the absence of the anterior fascia of the elytra, it differs in having the elytra rather less widened in the apical region, and less undulating above. The thorax has generally the sides broadly margined with yellow, but in some specimens it is almost entirely black. With regard to the three foregoing species, C. typicum, C. dorsale, and C. divisum, it must be observed that the synonymy given in Dr. Le Conte's ' List of Coleoptera of N. America,' and followed in Gemminger and Harold's Catalogue of Coleoptera, is evidently incorrect. C. apicale, Le C., is placed as a variety of typicum; and in the footnote Dr. Le Conte states that "( from some clerical error in the description, divisa, Newman, is irrecognizable, but is probably the same as apicalis, Le C." The clerical error alluded to is that Newman wrote "elytra basi nigro," instead of " apice nigro." It is UENIA.-CELETES. 23 possible that divisum may be a variety of dorsale, but it is certainly not a variety of typicum. Secondly. C. dorsale, Newmn., is placed as a variety of retieztlatum, Fabr. (Syst. Ent., p. 203). The description of this latter does not, however, accord with dorsale. The expressions "1Statura P. [Pyrochroa] bicoloris, at duplo major," "1Elytra plana," "1sterno fiavo," are better applied to typicum than to dorsale. CAENIA..TNewm., E-ntom. Mag., 1838, v. p. 381. The species of this genus have the elytra ample, each with nine costae, the second, fourth, and eighth much more elevated than the others; the interstices are divided into quadrangular spaces by transverse nervures. Cmnia scapularis. (Plate VI. fig. 6.) Newm., Entomt. Mag., 1838, v. p. 881. Nigra, obscura; elytris postice dilatatis, singulis novemcostatis, interstitiis transversim reticulatis, humeris fulvis. Long. 32-51 lin. Hab. North America. Antennme strongly dentate. Thorax rather broad, the posterior angles very acute and diverging, the anterior angles sometimes pitchy yellow. Elytra each with nine fine costae, the second, fourth, and eighth more elevated, the interstices divided into square spaces by transverse -nervures; the shoulders more or less dull yellow. The type specimen is very small, and has the thorax entirely black. CELETES. Newm., Entom. Mag., 1838, v. p. 381. This genus is distinguished from Calopteron by the antennae of the males having the branches arising from the base of the j oints. The elytra have each four costae, the interstices with transverse nervures. Celetes basalis. (Plate VI. fig. 4.) Celetes basalis, Le Conte, Journ. Acad. Nat. Sci. Philad., ser. 2, i. p. 76. Celetes marginellus (Fabr.), Newman, Entom. Mag., 1838, v. p. 381. Atra; thoracis lateribus humerisque falvis, illo carinato, apice producto, angulis posticis valde productis; elytris nervis quatuor elevatis, interstitiis transversim reticulatis. Long. 3-4 lin. Hab. North America. 24 LYCIDES. Black, or slightly fuscous. Elytra only slightly wider at the apex; each elytron with four costae, the interstices divided into square or slightly transverse spaces by transverse nervures. The fourth to tenth joints of the antennae in the male emit from the base a somewhat long, slender, compressed branch. The female has the antennae strongly dentate, and the thorax is strongly constricted in the middle, which causes the posterior angles to appear much more diverging. EURREACUS. Rostrum none. Apical joint of the maxillary palpi elongate, cultriform. Antennse long, the third to tenth joints each with a long, compressed branch springing from the base of the joint. Thorax with a mesial carina, which is doubled in the middle. Elytra pubescent, parallel; each elytron with nine costae, only four distinct, the interstices with a single line of punctures. The cultriform apical joint of the palpi and the flabellate antennae at once separate this from Emplectus, after which it should be placed. Eurrhacus tristis. (Plate VI. fig. 5.) Lycus (gen. 14) tristis, Waterk., Trans. Ent. Soc., 1878, pp. 99, 106.

Long. 5 lin. Hab. Cuenga, Ecuador. Dull black, the base of the palpi and base of the legs testaceous. Thorax with the margins finely reflexed, the disk with a mesial carina which divides and encloses a narrow elongate areolet in the middle, and then again becomes a single carina just before the posterior margin. Each elytron has nine costce, the second, fourth, sixth, and eighth only distinct, the others are very fine; the punctures in the lines are rather small, slightly transverse. LYPONIA. Waterh., Trans. Ent. Soc., 1878, p. 99. Rostrum none. Teguments thin. Antennae with long stout branches to the joints. Thorax subquadrate, with a mesial impressed line on the disk. Each elytron has nine costae, the alternate ones more conspicuous, the first, second, and third not reaching the apex, the fifth and seventh joining the sixth some distance from the apex; the interstices with transverse nervures. PLATEROS. 25 Lyponia debilis. (Plate VI. fig. 9.) Waterh., Trans. Ent. Soc., 1878, p. 107. Rubro-fusca; thorace limbo elytrisque rufis, antennis fere nigris, scutello piceo; elytris quadricostatis, interstitiis biseriatim fortiter punctatis, punctis transversis, seriebus costa tenui divisis. Long. 42 lin. Hab. China (J. C. Bowring, Esq.). Thorax rather flat on the disk, with a mesial fine impressed line (not extending to the anterior nor posterior margins), the sides gently reflexed. Elytra with the fourth, sixth, and eighth costse extending to the apex, by which means the first, second, and third are somewhat abbreviated; the fifth and seventh costse join the sixth some distance from the apex, the ninth is only visible at the shoulder when viewed laterally; the interstices have each a single line of strong, transverse punctures. The texture of the elytra is delicate, and is semitransparent where the punctures are. The third joint of the antennae has only a short branch, but the branches to the following joints gradually increase in length, are slender and lamelliform. PLATEROS. Bourgeois, Comptes-rendus d. 1. Soc. Ent. Belg., 1879. Lycus, genus 18, Waterh., Trans. Ent. Soc., 1878, p. 100. Rostrum none. Antenne slender and simple in both sexes. Thorax even above, with only a slight longitudinal mesial impression behind. Elytra with nine costse, the interstices with a single line of punctures. In my original manuscript the genus Plateros was intended only to include Eros lictor, Newm., and other American species; a more detailed examination of the species, however, has induced me to include in it the Asiatic forms separated originally under the head of c" Genus 16" (Tr. Ent. Soc., 1878, p. 99), of which gracilis was the type. AMERICAN SPECIEs. Plateros lictor. (Plate VIII. fig. 5.) Eros lictor, Newm., Entom. Mag., 1838, v. p. 382.

Antennse relatively shorter than in the preceding; the third joint at its apex a little broader than its length, narrowed towards the base; the fourth joint nearly as long as the second and third taken together, but not wider than the second, narrowed at the basal half; the following joints very gradually becoming narrower and a trifle longer. Thorax not quite so short as in lictor, more rounded in front, the posterior angles a little less diverging. Elytra relatively a trifle less long, the shoulders margined with dark reddish yellow. The coxae and the extreme base of the femora yellowish. The species of this group are very variable, and it is difficult to arrive at any definite conclusion as to the identity of the species described by Newman with those of other authors. I think, however, that there is little doubt that alatus, N., is the female of lictor, N., corresponding respectively to timidus, Le C., and ceger, LeC., which, according to Dr. Le Conte himself, are synonymous with modestu of Say (Bost. Journ., i. p. 153). See Le Conte, Journ. Ac. Phil. ser. 2, i. p. 80, and List of the Coleopt. of N. Amer. p. 51. The reference in Gemminger and v. Harold's Catalogue of Coleoptera,' p. 1634, which assigns alatus to crenatus, Germ., is incorrect, as it is also in the journal above quoted, at p. 79. ASIATIC SPECIES. Plateros dispellens.

Elytra rather PLATEROS. 27 strongly punctate-striate, the intervals all equal and somewhat costiform; the apex is more or less black. I believe that the species described by me as Lycus (gen. 16) gracilis (Trans. Ent. Soc. 1878, pp. 99 & 107) is only a variety of the above, having the elytra entirely yellow. Plateros planatus.

Shanghai (Fortune), Penang (Cantor). Antennae a little stouter than in the preceding species, broadest at the middle, tapering towards the apex; the third to sixth joints are a little more dentate in the male than in the female. Thorax shining, the sides gently reflexed, the front margin with a few punctures. Scutellum yellow. Elytra rather strongly and closely punctate-striate, the intervals very narrow, nearly equal, the fourth a little more elevated at the base. The inside of the base of the femora yellowish. This species is very close to the preceding, but (besides the difference of coloration) it differs in having the sides of the thorax less reflexed, and the posterior angles are more rectangles. Plateros languidus. (Plate VII. fig. 2.) Obscure fuscus, pubescens, parallelus, depressus; capite flavo; thorace flavo, depresso, marginibus incrassatis vix reflexis, disco foveolis quinque parvis impresso; elytris crebre evidenter punctatostriatis, interstitiis angustis, alternatim parum elevatis. d.

Thorax reflexed at the sides, deeply impressed on each side of the disk, with a slight longitudinal impression in the middle of the hind margin. Elytra parallel, rather strongly and very closely punctate-striate, the interstices very narrow and very nearly equal; the shoulders are tinted with dull yellow. In the Museum collection there is a single specimen from India, in bad condition, of a species closely allied to the preceding. It differs in having the antennae decidedly more dentate and not quite so long, and the thorax is not so much impressed on the sides of the disk; the punctate striae of the elytra are not quite so strong. It is a male, and measures 24 lines. Plateros expletus. (Plate VII. fig. 4.)

Elytra closely punctate-striate; the interstices very narrow, only distinct at the base, lost among the punctuation at the apex, the extreme apical margin dusky. Coxea and the base of the anterior and intermediate femora yellowish. Plateros carbonarius. (Plate VII. fig. 5.)

Very close to P. fuscipennis, from which it differs in being more elongate; the thorax is relatively a little longer and nearly parallel at the sides, not so deeply impressed on each side of the disk, and the fuscous disk is more distinct, only leaving the borders yellow; the punctuation of the elytra is also more rugose and less regular; there is no trace of yellow on the shoulders. DIHAMATUS. 29 Plateros chinensis. (Plate VI. fig. 7.) Nigro-fuscus, parce pubescens; subparallelus; thorace nitido, lateribus rufo-flavis; elytris sat fortiter punctato-striatis, interstitiis angustissimis, fere squalibus, postice obliteratis. c,. Long. 3 lin. Hab. Hong Kong (J. C. Bowring, Esq.). Very close to P. fuscipennis, but relatively a little broader, and the antennse are shorter and rather stouter. The thorax is broad, a little narrowed in front, fuscous; the disk is moderately impressed on each side at the base. The elytra are rather roughly and very closely punctate-striate, the intervals very narrow, interrupted by the punctuation towards the apex. The anterior coxae are pale. The female has the antennae a trifle shorter and stouter than the male. DIHAXMATUS. Antennae slender, scarcely dentate, the second and third joints nearly equal. Thorax simple, with a short longitudinal mesial channel behind. Elytra with ten punctured strife; the interstices very narrow, nearly equal, costiform. Differs from the preceding genus in having the third joint of the antennae small. Dihammatus cribripennis. (Plate VII. fig. 6.) Pallide fuscus; capite, thorace elytrorumque humeris sordide flavis; elytris crebre punctato-striatis. d. Long. 2 lin. Bab. Java (J. C. Bowring, Esq.). Parallel, depressed. Antennae rather long and slender, the third joint scarcely longer than the second. Thorax rather deeply impressed on each side of the disk, with a longitudinal mesial channel extending from the base to a little before the middle; the anterior margin obscurely punctured. Elytra closely and distinctly punctate-striate; the interstices very narrow, subcostiform, nearly equal, the alternate ones a little more distinct at the base. Coxae and base of the femora obscure yellow. Dihammatus pallens. (Plate VII. fig. 7.) Parallelus, depressus, sordide flavus, pubescens; antennis, elytris abdomineque fuscescentibus; elytris crebre subtilius punctatostriatis, interstitiis angustissimis. Long. 2 lin. Hab. Sarawak (Wallace). 30 LYCIDIE. Closely resembles the preceding, but has the elytra more finely sculptured &c. Antennae fuscous; the first and second joints yellow, the third joint scarcely larger than the second. Thorax pale yellow, with two impressions on each side within the lateral margins; the mesial posterior channel fine, the anterior margin obscurely punctured. Elytra pale fuscous, with a tinge of yellow around the base, closely and more finely punctate-striate than in the preceding species; the interstices extremely narrow, the second and fourth a little more distinct at the base. Abdomen fuscous. Part of the femora, the tibiae, and tarsi slightly fuscous. This species must not be confounded with Plateros expletus above described, which it closely resembles. The small third joint of the antennae at once separates it. MELAMPYRUS. Rostrum none. Antennae serrate, moderately broad. Thorax even above, with a mesial longitudinal impression behind. Elytra with nine costee, the alternate ones more elevated. Thorax and elytra pubescent. This genus is proposed for two species which differ from Plateros chiefly in being more pubescent and in having the antennae broader. From Ditoneces they differ in having the alternate costae of the elytra more elevated. Melampyrs alternans. (Plate VIII. fig. 7.) Lycus (gen. 19) alternans, Waterh., Trans. Ent. Soc., 1878, pp. 100 & 108. Ater; antennis latis, dentatis; thorace antice omnino rotundato, medio postice longitudinaliter impresso, angulis posticis acutiusculis; elytris dimidio basali ferrugineo, novemcostatis, costis alternatis elevatis, interstitiis uniseriatim punctatis. L. Long. 41 lin. Hab. Sarawak (Wallace). Having only the female of this species, its position is a little doubtful; its appearance is rather different from that of the species of Ditoneces, owing chiefly to the elevated alternate costae of the elytra; but if the male should be found to have pectinate antenna, it may have to be associated with that genus. Melampyrus misellus. (Plate VIII. fig. 6.) Lycus (gen. 19) misellus, C. Waterh., Trans. Ent. Soc., 1878, pp. 100 & 108. Nigro-fuscus, pubescens; thorace, scutello elytrisque rufis; antennarum articulo apicali ferrugineo; thorace medio longitudinaliter DITONECES. 31 canaliculato; elytris novemcostatis, costis alternatis elevatis, interstitiis uniseriatim punctatis. L. Long. 3 lin. Hab. Penang (Jr. C. Bowring, Esq.). The remark appended to the foregoing species applies also to this. The colour of the thorax and elytra is a somewhat pale rusty red; the extreme apex of the elytra is a little dusky. DITONECES. Rostrum none. Antennae of the male with a slender pubescent branch emitted from the third to tenth joints. Thorax even above, with a very short longitudinal impression behind. Elytra pubescent, with nine nearly equal costa, the interstices each with a single line of punctures. The females differ from the males in having the antennae only strongly dentate. The species known at present are all eastern. Ditoneces punctipennis. (Plate VII. fig. 10.) Lycus (gen. 17) punctipennis, C. Waterh., Trans. Ent. Soc., 1878, pp. 100 and 108.

'd. Long. 4 lin. Hab. Java (J. C. Bowring, Esq.). This species differs from the preceding in having the thorax rather longer and in having the branches emitted from the antennal joints shorter, the branch of the sixth joint being about half the length of the joint, whereas in D. punctipennis it is rather longer than the joint. 32 LYCIDAE. Ditoneces propinquus. (Plate VII. fig. 11.)

Long. 34 lin. Hab. China (J. C. Bowring, Esq.). Very near the preceding, but of a sordid yellow colour above; the thorax a little narrowed in front and completely rounded anteriorly, the disk dusky, moderately impressed on each side. The antennae are nearly as in D. rufescens, but the joints are a little shorter. Elytra strongly punctate-striate; the interstices extremely narrow, the alternate ones a little more distinct and more elevated, especially the fourth and sixth. Ditoneces sobrinus.

Hab. Burmah (J. C. Bowring, Esq.). Differs from the three preceding species in having the punctuation of the strike of the elytra less strong and more obscure, the interstices being a little less narrow, and all equal except the eighth, which is a little more elevated. The antennae have the branches to the sixth and seventh joints about as long as the joints. The usual short channel in the middle at the base of the thorax is scarcely noticeable.

This species is densely pubescent above. The punctures in the strise of the elytra are rather large and close, but are much obscured by the pubescence; the interstices are extremely narrow and all equal. The male has very long branches to the antennal joints, at least three or four times the length of the joints. The female has the antennae very strongly dentate. The type specimens to which Mr. Walker gave the above-mentioned names clearly belong to one species; his revocans is a small D1TONECES. —DITUA. 33 male. The specimen named duplex is a little narrower than the other female examples, but is clearly the same species; the alternate interstices of the elytra are a little more distinct than the others. Ditoneces pubipennis. (Plate YIII. fig. 1.) Lycus pubipennis, Walker, Ann. 8 Mag. n. Hist., 1859, iii. p. 269.

S. Long. 3 lin. Hab. Ceylon. This species is closely allied to D. pubicornis, but has the thorax black and rather shining, deeply impressed on each side. The alternate interstices of the elytra are slightly costiform, the others are extremely narrow and somewhat obscured, and interrupted by the rather strong punctuation of the stri.e. Celetes scabripennis, Motsch. (Bull. Mosc., 1861, i. p. 137), belongs to this genus, and should come here. It is much smaller than any of the preceding (13-24 lines long), and has the elytra pale yellow, with the apex black. The thorax has a fovea in the middle at the base, and is impressed on each side. The elytra have the striae rather more finely punctured than any of the preceding species; the alternate interstices are slightly elevated, the others are very narrow and somewhat interrupted by the punctures of the striae. The male has the branches of the antennal joints slender, a little longer than the joints themselves. The female has the antennae rather strongly serrate. The specimens in the Museum are from Ceylon. Ditoneces terminalis. (Plate VIII. fig. 3.)

Long. 2k lin. Hab. Ceylon. Very close to D. scabripennis, Mots., but the antennae, compared with the female, appear rather more dentate, the thorax is straighter at the sides, and the punctuation of the striae of the elytra is rather stronger and the interstices are all equal. DITUA. Rostrum none. Antennse broad, serrate. Thorax broad, a little more than a semicircle, the margins not incrassate, with a discoidal D 34 LYCIDME. lanceolate areolet, from the lateral angle of which proceeds an oblique carina, which is scarcely noticeable. Elytra with nine regular nearly equal coste; the interstices with a single line of punctures. Legs rather short. Thorax, elytra, and legs having a woolly appearance. The form of the thorax and the presence of a mesial areolet separate this from the foregoing genera. Ditua deplanata. (Plate VIII. fig. 8.) Lycus (gen. 20) deplanatus, Waterh., Trans. Ent. Soc., 1878, pp. 100 and 109.

Long. 4 lin. Hab. New Guinea, Dorey (Wallace). The basal joint of the antenne is dusky. The thorax besides the mesial areolet has an indication of a raised line on each side from the middle of the areolet not quite reaching the sides of the thorax. BULENIDES. Rostrum none. Antenne broad, dentate. Thorax with the margins incrassate, with a distinct discoidal areolet, united to the anterior margin by a carina. Elytra with four distinct costae; the interstices with two lines of punctures divided by a fine costa. Differs from the preceding genus in having the margins of the thorax more or less reflexed and incrassate, and in the costae of the elytra being unequal. This genus was originally proposed for Lycus obsoletus, but three others are now associated with it. Bulenides obsoletus. (Plate IX. fig. 1.) Lycus (gen. 21) obsoletus, Waterh., Trans. Ent. Soc., 1878, pp. 100 and 109.

Long. 34-44 lina Hab. Java (J. C. Bowring, Esq.), Sumatra (Buxton). The extent of the darker apical portion of the elytra varies, but it occupies at least half of the elytra. BULENIDES. 35 Bulenides pauper. (Plate IX. fig. 2.) Fuscus, opacus; thorace ferrugineo-flavo, subtiliter pubescente, antice omnino rotundato, medio caring distincta postice duplicata; elytris basi ferrugineo-flavis, quadricostatis, sat fortiter biseriatim punctato-striatis, seriebus carina tenui diviis. d. Long. 44 lin. Hab. Sumatra. A rather dull, broad species. The antennae are robust and strongly dentate. Thorax transverse, broadest at the posterior angles (which are acute), impressed on each side; the mesial carina is doubled rather behind the middle. Elytra at the base not broader than the thorax, rather wider towards the apex; the extreme base and the four strong costse for half their length rusty yellow, rather strongly punctate-striate in double lines, the lines divided by a very fine costa. Bulenides turbidus. (Plate IX. fig. 4.) Nigro-fuscus, opacus; thorace rufo-ochraceo, crebre punctato, medio carina distincta postice duplicata, disco utrinque infascato; elytris quadricostatis, interstitiis biseriatim fortiter punctatis, seriebus linea tenui divisis.. Long. 5k lin. Hab. Sumatra. Rather more elongate than B. pauper, the thorax less transverse and less rounded in front. Thorax with the margins broadly reflexed and rather thickly punctured; the mesial carina is very distinct, divided posteriorly into two parallel carinae. Elytra each with four strong costre, the interstices with two rows of strong (slightly transverse) punctures, the rows divided by a fine line which is scarcely raised. Bulenides dubius. (Plate IX. fig. 5.) Fuscus, parum nitidus; thorace fusco-testaceo, lateribus parum reflexis, disco utrinque fortiter impresso, antice carina brevi, medio areola lanceolata; elytris basi plus minusve fusco-flavis, quadricostatis, interstitiis biseriatim punctatis, seriebus basi costa tenui divisis. Long. 3 lin. Hab. Borneo. Thorax obscure testaceous, rather dusky at the base; the carina is scarcely perceptible in front, and is divided posteriorly into two. Elytra parallel, fuscous, paler at the base; each elytron with four distinct costse, which turn slightly away from the scutellum near the base; the interstices with two lines of moderately strong punctures, the D2 36 LYCID3. lines divided at the base by a very fine carina; the outer line of punctures has a tendency to encroach on the inner line, and towards the apex the lines are somewhat confused. It is doubtful to which sex the specimen described belongs. CAUTIRES. Rostrum none. Antennee of the male with a long compressed branch proceeding from the base of the third to tenth joints; very strongly dentate in the female. Thorax with seven areolets, the two lateral ones sometimes obsoletely divided. Elytra as in Bulenides. The males of this genus are easily known by the branches of the antennal joints arising from the base of the joints. The females have the antennse very acutely dentate. Cautires excellens. (Plate VIII. fig. 9, & Plate IX. fig. 3.) Lycus (gen. 22) excellens, Waterh., Trans. Ent. Soc., 1878, pp. 101, 110.

The lateral areolets of the thorax are sometimes not very distinctly divided, but the ridge separating them is generally well marked. The elytra have each four costse, the interstices with two rows of black punctures, the rows divided by a fine line, not by a distinct costa. Cautires excellens, var. $. This variety (as it seems best to consider it for the present) differs from the female of C. exccellens from Borneo in being rather smaller, in having the base of the elytra more red, but especially in having the joints of the antennae differently formed; the branches arise from the base of the joints, and not from the apex, being thus somewhat intermediate in form between the male and female of the Bornean examples. Hab. Sumatra (Buxton). Cautires congener. (Plate IX. fig. 7.) Fuscus, subopacus; thorace ochraceo; elytris basi ochraceis, quadricostatis, interstitiis biseriatim sat fortiter punctatis. c, Yi.

Elytra very little enlarged towards the apex, obscure ochraceous at the base; each elytron with four well-marked coste, the interstices with two rows of rather strong and distinct punctures, the rows divided by a fine (but scarcely elevated) line.. Larger than the male (44-5 lin.), the thorax and elytra of a clearer yellow. It somewhat resembles Metriorrhynchus astutus; but the discoidal areolet of the thorax is narrow, elongate lanceolate, and the elytra have scarcely any pubescence. EROS. Newoman, Entom.

Second joint of the antennae small, but distinct, the third joint of the same form, but one third larger; the fourth as long as the two preceding taken together, and (at its apex) a little thicker; the following joints of the same form as the fourth, but becoming more slender. Thorax somewhat transverse, rather strongly constricted before the posterior angles, which strongly diverge and are acute; the mesial areolet is very broad, it nearly extends to the anterior and posterior margins, and is connected at the sides by an oblique carina on each side. The elytra have a reddish-yellow spot on the humeral angle; each elytron has seven costae, the second, fourth, and sixth much stronger than the others; the intervals have well defined transverse nervures which divide the surface into squares or only slightly transverse spaces. EROTIDES. Rostrum none; forehead produced into a process between the antennae. AntennEe simple; the second joint small, but distinct. Thorax trapezoidal, with seven areolets as in Platycis minutus. Elytra parallel; each elytron with four strong costee; the interstices with transverse costae, which are placed somewhat close together, frequently oblique, or divided so as to form the letter Y placed horizontally -<. The type of this genus is Eros oblitus, Newman. It approaches most nearly to Platycis, but the sculpture of the elytra is quite 38 LYCID.-. different.

North America. Forehead produced between the antennae into a flattened process, which is slightly concave above, truncate in front; it is a little broader in the female than in the male. Thorax rather broader than long, with the sides reflexed; the surface is divided into seven areolets, the discoidal ones shallow, the lateral ones deep; the three anterior carinse are parallel, the outer ones of these three are continued posteriorly and curved somewhat in the form of reversed brackets ) (, so as to enclose the posterior mesial areolet, which is closed posteriorly by the base of the thorax. The elytra are subparallel, each with four very well-marked shining costae; the interstices have numerous rather less elevated transverse shining ridges, which are either straight, oblique, or divided into two halfway across the interstice. XYLOBANUS. Rostrum none. Antennae dentate. Thorax with five or seven areolets, the lateral ones sometimes obliterated. Elytra each with four costs, the interstices with regular transverse coste.

C. Bowring, Esq.). It is perhaps doubtful whether this should be separated from the preceding. It differs, however, in having the thorax and elytra of a uniform colour, the antennae are much more strongly dentate, the thorax does not present the same roughness in front, and the transverse costas of the interstices of the elytra are further apart, the spaces divided by them being nearly squares, even in the lateral interstice. Xylobanus foveatus. (Plate X. fig. 2.) This species differs from the preceding in having the thorax and elytra of a dull yellowish red. The antennae are very strongly dentate; the thorax has the posterior angles not diverging, and the mesial posterior areolet, instead of terminating in the middle of the disk, extends much more forward. Hab. India, Barrackpore? (Sir J. Hearsay). Xylobanus rubens. (Plate X. fig. 4.)

Bowring, Esq.). This only differs from X. fastidiosus above described in the thorax. This is shorter and more rounded in front, and instead of having seven areolets, it has only one narrow mesial one, which is joined to the anterior margin by a carina. It seems very probable that this may be a variety of X. fastidiosus. Xylobanus senex. (Plate X. fig. 7.)

Long. 4 lin, Hab. Borneo (Wallace). This differs from X. humilis in the thorax, which is shorter and more obtuse in front, and instead of having seven areolets, has only five, the mesial posterior one being extremely narrow. It is very probable that this may only be a variety of X. humilis. 42 LYCID2!. Xylobanus elusus. (Plate X. fig. 9.)

Batchian (Wallace). Thorax yellow, with a broad black mesial stripe, the anterior border and the margins obscurely punctured. Elytra with the four costse distinct; the interstices have a dull woolly appearance, very obscurely punctured, with very numerous fine transverse costae, which are rather close together but somewhat irregular. This and the following species are somewhat aberrant forms, and are therefore placed at the end of the genus. Xylobanus mixtus. (Plate XI. fig. 5.) Brevior, atro-fuscus, opacus, pubescens; thorace septemareolato; elytris quadricostatis. Long. 31 lin. Hab. Waigiou (Wallace). Dark fuscous, with the incrassated lateral margin of the thorax rather paler. The posterior angles of the thorax are slightly diverging and acute; the seven areolets are well defined. Each elytron has four distinct costse, and in the first and fifth interstices, as well as at the base of the second, third, and fourth, a fine intermediate costa may be traced; the interstices have numerous transverse costae, placed somewhat close together, dividing the surface into strongly transverse quadrangular spaces, except the first and fifth interstices and the extreme base of the others, which have two rows of irregular punctures, these rows being divided by the fine intermediate costae above mentioned. This species is of particular interest, on account of its showing the commencement of the intermediate costse on the elytra met with in Metriorrhynchus. PORROSTOXA. Castelnau, Silbermann's Mev.

The rostrum is very smooth, only punctured at the sides and at the base. The four anterior femora are tipped with black; the posterior pair are black, except at the extreme base. The middle posterior areolet of the thorax is black anteriorly. The sculpture of the elytra is more regular and distinct; two of the costae are very strong at the base. Porrostoma apicale.

Elytra yellowish, with the interstices dusky and with a double series of square punctures, the rows are not distinctly divided by a ridge. Since this species was originally described I have found that Omalysus lineatus, Hope, then unknown to me, belongs to this genus, so that the name lineatum has to be changed. Metriorrhynchus togatus.

The elytra parallel, with the extreme apex dirty yellow; the four coste on each elytron are distinct, but the third is less so towards the apex; the interstices have rather closely placed irregular transverse ridges, which are frequently oblique, or when half across the interstice divide into two, forming a Y placed horizontally (>-), giving a reticulated appearance to the elytra; here and there the intermediate very fine longitudinal costse may be traced. Metriorrhynchus fallax. (Plate XII. fig. 5.) Porrostoma fallax, Waterh., Trans. Ent. Soc., 1877, p. 79, pl. i. figs. 57-60.

Elytra quadricostate; the interstices with two METRIORRHYNCH8US. 49 rows of punctures, the rows separated only at the base of the elytra by an obscure costa. The female differs from the male in having the antennae a little less strongly dentate. It is difficult to decide whether Lycus rufipennis, F., should be considered identical with P. erythropterum, Er., or with P. salebrosum, W. I have here adopted Erichson's view, by which the latter becomes synonymous with the Fabrician species. Metriorrhynchus hamorrhoidalis. Porrostoma heemorrhoidale, Waterh. Trans. Ent.

Elytra with the four costse distinct; the interstices with two rows of large irregular punctures, the rows not divided by a distinct costa; the apices are red. This species resembles M. scalaris, but is much longer and narrower, and the rows of punctures on the interstices of the elytra are much more regular. Lycus atratus, Fabr. (Syst. El., ii. p. 113) may perhaps be a black variety of this species, and both are possibly varieties of rufipennis, F. Metriorrhynchus plagiatus. (Plate XII. fig. 8.)

Elytra parallel; each elytron with four complete strong costa-,, and four intermediate ones at the base; the first and second of the intermrediate costae are traceable nearly to the apex of the elytra; the interstices are closely punctured. The ridges which divide the thoracic areolets are very obtuse. In the British-Museum collection are several specimens of a species from Celebes which I have determined to be Lycus tlhoracicus, iFabr. (Syst. El., ii. p. 117), with which M21. cyanopterus, Redt., seems to be synonymous. X. flavicollis differs from the-se in having the elytra black, the thorax is more convex on the disk, the sides are less reflexed, and the mesial areolet is very strong and deep; whereas in M. thorcacicus the mesial areolet is almost obliterated. The elytra are very similar in sculpture, but in thoaius the interval between the third and fourth costte has two lines of very close transverse punctures which meet in the middle of the interstice; in Jlavicollis the punctures in this interstice are less straight, transversely ovate, and they do not meet so closely in the middle of the interstice.

Elytra each with four strong costse, which are broader at the base; the interstices with two lines of crowded punctures, which are small and round at the base (where the lines are divided by a fine costa), but rather more transverse and confused towards the apex; near the apex the lines are divided by a fine costa; all the costse are rusty red for at least half their length. Varieties. Thorax with the elevated lines rusty yellow, or with the entire thorax red. One specimen from Penang has the elytra almost entirely yellow, with only the apex black, the punctures dusky. I think there can be no doubt that this is the Diet. lineatus, Kirsch; that author's name is, however, most unfortunately preoccupied for a species named by Hope. It appears somewhat doubtful whether this should be separated as distinct from Lycus inaequalis, Fabr.* (Syst. El., ii. p. 112). The specimens in the Museum collection which I have determined to be the Fabrician species average a little larger; the strong costae of the elytra are of equal thickness throughout, and the intermediate costse are very fine, not more elevated at the base, and are visible throughout the whole length. Metriorrhynchus kirschii, var.? (Plate XII. fig. 10.) This differs from what I have above described as M. kirschii in having the mesial areolet of the thorax more obtuse in front and more removed from the anterior margin; the intermediate costse of the elytra are distinct and equal throughout their length. The base of the femora and the base of the tibiae are yellow, as is also the sternum. Hab. Batchian. Metriorrhynchus rusticus. (Plate XIII. fig. 2.)

Long. 10 lin. Hab. Ternate, Batchian. This species is very distinct on account of the elytra being less parallel than in any of the foregoing, slightly widened towards the apex. The transverse costae of the interstices of the elytra are extremely close and distinct, with the intervals between these costr scarcely as much as the thickness of the costae themselves. Abdomen slightly bluish black. Metriorrhynchus philippinensis. (Plate XIII. fig. 4.) M. cribripenni affinis; angustior, thorace paulo longiori; scutello apicem versus angustato, apice exciso; abdomine nigro-cyaneo. Long. 4|-8 lin. Hab. Philippine Islands (H. Cuming). Very close to the preceding, but rather narrower, of a rather deeper ochraceous colour, the thorax a little more elongate, the mesial areolet narrower. Scutellum narrowed towards the apex, deeply but more narrowly excised at the apex. Elytra similarly sculptured to the preceding; but the elytra being a little narrower, the interstices are narrower, and consequently the transverse costs are shorter. The abdomen and sterna are brighter steel-blue-black. Metriorrhynchus sericeus. (Plate XIII. fig. 5.) Elongatus, parallelus, ater; antennis brevioribus; thorace, scutello elytrisque ferrugineo-ochraceis, his parallelis, octocostatis, costis intermediis parum elevatis, interstitiis crebre transverse costatis; abdomine nigro-cyaneo. d,.

Elytra with the interstices very silky, with closely set transverse costae; the spaces between these costse rather less than the thickness of the transverse costse themselves. The male example has the sculpture much obscured by the fine silky pubescence, which makes them appear more roughly punctured. Metriorrhynchus sericeus, var. This differs from the foregoing in having the thorax ochraceous, the elytra yellow, with the extreme apex fuscous; the apex, too, is more obtuse. Hab. India (from Children's coll.).

Metriorrhynchus immersus. (Plate XIII. fig. 1.) Elongatus, ater, supra opacus; thorace nigro-cyaneo, areolh discoidali latissima; elytris basi flavis. cT,. Long. 4~-71 lin. Hab. Aru I. and Dorey (Wallace). Very close to M. ephippiger, Guerin, but appears to be distinct. The basal third only of the elytra is yellow, and the line of demarcation is very sharply defined and nearly straight. The thorax is more distinctly blue-black, and the mesial areolet is very broad at the anterior third, at which part it occupies one third the width of the thorax. The elytra have each the same eight costae, the intermediate ones being scarcely raised; the punctures in the interstices are sometimes round, and in the broader females they are close and strongly transverse. The male example is much smaller than the female, and has the scutellum yellow. The specimen in the Museum collection which has been determined to be M. ephippiger, Guerin (Voy. Coquille, p. 73), is from Dorey; it is a male, and measures 6k lines in length. There is another specimen from Waigiou, a female, which differs 54 LYCIDXE. from that from Dorey in being relatively considerably shorter; the discoidal thoracic areolet is extremely narrow; the elytra have the lines of punctures rather stronger, and the punctures are more transverse. This specimen may prove to belong to a distinct species. Metriorrhynchus nobilis. (Plate XIII. fig. 3.) Elongatus, ater, opacus; antennis sat brevibus; thorace septemareolato; elytris octocostatis, interstitiis crebre fortiter punctatis, apice late flavo.. Long. 5 lin. Hacb. New Guinea (Wallace). Thorax rather small, the mesial areolet nearly extending to the anterior margin, moderately broad before the middle. Elytra with the eight costae very distinct, the alternate ones less elevated in the middle of the elytra, but equally distinct at the base; the interstices have each a single line of close, strong punctures. The yellow at the apex of the elytra extends for rather more than one third of their length. At some little distance from the apex the fifth and seventh fine costee are united to the sixth; and the fifth and sixth, and the seventh and eighth lines of punctures become united, the punctures then being transverse. I believe these abbreviated costae to be a malformation; but the two elytra being exactly similar, it may be normal. Metriorrhynchus vagans. (Plate XIII. fig. 10.)

A much shorter species than any of the preceding, with very coarsely punctured interstices to the elytra. The thorax has the seven areolets very distinct, the posterior angles are acute and slightly diverging.

Torres Straits, Batchian, Aru I. The thorax has seven areolets, but usually the mesial lanceolate one only is distinct; the surface is rather roughly punctured, except the posterior part of the disk. Each elytron has eight costae, the alternate ones rather narrower and less elevated; the punctures in the lines are distinct and rather strong. The type specimen and other specimens from Australia have the disk of the thorax black. The other examples, from Aru I., Batchian, and Torres Straits, have the thorax entirely reddish yellow, except one example from Aru I., which has a little dusky mark. These specimens differ, moreover, in having the sterna and base of the fcmora also reddish yellow. The males have the antennae pectinate. In the females they are only dentate (Plate XIV. fig. 10). SYNCHONNUS. Rostrum none. Antennae dentate. Thorax with a lozengeshaped mesial areolet, which extends from the base to the anterior margin; from each lateral angle of this areolet there is a straight carina, which extends to the middle of the side; by this means the surface is divided into five areolets. Elytra with four costse, the interstices irregularly punctured. This genus is proposed for the reception of a single Australian species. Synchonnus clientulus. (Plate XV. fig. 2.)

Long. 4-6 lifn. Hab. Sumatra (Buxton). The male has the antenna) only slightly more dentate than in the female; they are rather broad, and of nearly equal width throughout in the typical specimen. In the British-Museum collection there are three female examples, which differ from the type in having the antennae less broad, less strongly dentate, more tapering towards the apex, and apparently, also, rather shorter; they have, moreover, the thorax entirely red. One of these specimens was received from Sumatra with the type examples, one is from India, and the other from Java from Mr. Bowring. There is also a single example, without locality, having the red thorax, which has the antennee broad, as in the type example. It seems best, at least for the present, to consider these specimens varieties of the same species. The example which I named M. velutinus (Trans. Ent. Soc., 1878, p. 110) has the mesial areolet of the thorax black, and the antennae less robust; but I believe this will prove to be a variety of C. signicollis, Kirsch. Conderis major.

Of the four costae on the elytra, the second and fourth are the more distinct, but none of them extend to the apex; the interstices have very numerous transverse ridges, which are very irregular and sometimes interrupted; towards the apex of the first interstice and in the fifth there are indications of an irregular intermediate longitudinal costa.

Long. 4 lin. Hab. Waigiou (Wallace). Thorax a little narrowed in front, the sides somewhat straight; the four anterior areolets nearly equal, the incrassate margins testaceous, the elevated lines pale pitchy. Scutellum deeply emarginate at the apex. Elytra a little narrowed in their middle, with the four costae fine, the second and third slightly turn from the scutellum near the base; near the base and at the apex a very fine short costa may be seen between each pair of the complete coste, but those at the apex are very obscure. This species is somewhat aberrant in this genus on account of the costae of the elytra not being parallel to the suture near the base. The branches of the middle joints of the antennae are about six times as long as the joints themselves. ENICLASES. Antennae long, somewhat dentate. Thorax narrow, with seven areolets, the two lateral ones imperfectly divided; the posterior angles acute, prominent. Scutellum somewhat rounded posteriorly, with a small notch at the apex. Elytra with seven costae, the first trifurcate at the base; interstices with a single line of punctures. Legs very long, compressed.

TRICHALUS. Waterh., Trans. Ent. Soc., 1877, p. 82. The species of this genus resemble those of Metriorrhynchus, but have only a single discoidal lanceolate areolet to the thorax, and the elytra have the first costa divided into three at the base; or, in other words, they have nine costse, the first and third being abbreviated and united to the second not far from the base, so that there are only seven costae posteriorly.

The first strong costa is joined by its two fine companions at not more than one-sixth the length of the elytra; the punctures in the lines are generally square, but they are very irregular. There is a male example from Aru Island, which I think may prove to be distinct from T. niger; the thorax is more rounded in front, the posterior angles more diverging; the elytra have the fine lines dividing the rows of punctures almost wanting, and the strong costae are more developed.

The apex of the elytra and the abdomen are now wanting in the type specimen, which is the only one I have seen. In the Banksian collection. Trichalus cyaneiventris. (Plate XVII. fig. 6.) Cyaneo-niger, subtus nitidus; antennis atris; thorace flavo, antice angustato, lateribus reflexis, angulis posticis acutis; scutello flavo; elytris flavis, opacis; prosterno mesosternoque flavis. c, 9. Long. 72-9 lin. Hab. Philippine Islands (Cuming). Thorax dull yellow, much narrowed anteriorly, the posterior angles diverging and acute, mesial arcolet extending from the base to the anterior margin. Elytra subparallel in the male, considerably expanded at the apex in the female; the first strong costa is joined by its two finer companions nearly at the middle of the elytra; the punctures in the lines are well defined, rather close, and strongly transverse. ENYLUS. Antenn~e compressed, linear. Thorax with a mesial lanceolate areolet. Elytra parallel, each with eight costae; the fourth and eighth distinct, and extending to the apex; the second and sixth only distinct at the base, indistinct posteriorly; the others very narrow and indistinct, the interstices each with a single line of punctures. This genus is proposed for a single species which closely resembles some species of Trichalus, especially T. griseus, but has parallel costae to the elytra. Enylus segregatus. (Plate XVII. fig. 10.) Testaceus; antennis fuscescentibus; capite, elytris abdomincque fuscis; elytris singulis costis quatuor, interstitiis crebre punctatis. d. Long. 2J lin. Hab. Mysol (Wallace). STROPHICUS. —METAN(EUS. 73 Antenne dusky, linear. Thorax pale yellow, subquadrate (the anterior margin arcuate); the anterior and lateral margins closely and rather roughly punctured; the mesial areolet very shallow, extending nearly to the front margin. Scutellum fuscous. Elytra parallel, fuscous, rather paler towards the base; the second and fourth costie complete, the first and third not extending beyond the middle of the elytra, the intervals with four lines of close, small punctures. STROPHICUS. Antennae linear. Thorax with a single lanceolate mesial areolet. Elytra parallel; each elytron with four distinct costae, the third abbreviated posteriorly; the interstices with punctures, which are divided from each other by transverse carinw; these punctures are, here and there, in double lines, but they are generally transverse and extend across the whole interstice. It is somewhat doubtful whether this genus should be placed after Xylobanus or Trichalus; the linear antenna and general form, however, make the latter position appear preferable. Strophicus nigellus. (Plate XVII. fig. 11.) Fuscus, subopacus; thorace trapezoidali, lateribus baud reflexis; singulo elytro quadricostato, costa tertia postice obliterate, interstitiis sat fortiter punctatis. -. Long. 22 lin. Hab. Mysol (Wallace). Thorax with the mesial areolet very distinct and elevated. Elytra parallel, the third costa much obliterated behind the middle; the first and second intervals have two lines of rather strong, clear (but unequal sized) punctures; beyond the middle these punctures frequently coalesce laterally, so that posteriorly there appears to be only a single row of transverse punctures; the third and fourth intervals have two lines of punctures. METAN(EUS. Eyes large. Antennae long, with the third to tenth joints in the male each with a long compressed branch arising from the base. Thorax pubescent, with seven shallow impressions. Elytra pubescent, with four parallel costse; the interstices each with a line of obscure punctures on each side. Three species of this genus are at present known. 74 LYCIDIE. Metano~us dispar. (Plate XYIII. fig. 1.) Lycus (gen. 37) dispar, Waterk., Trans. Ent. Soc., 1878, p. 115. Elongatus, nigro-fuscus, griseo-pubescens; thorace impressionibus septem notato; scutello apice exciso; elytris sat convexis, sordide fiavis, apice infuscato, costis quatuor obtusis instructis, interstitiis angustis parum convexis. Long. 4k lin. flab. Malacca. Antennae blackish, with grey pubescence. Thorax grey-fuscous, with paler pubescence, the elevated parts paler; surface divided into seven areolets, the ridges dividing them blunt and not well defined; there is also a round fovea within each anterior lateral areolet. Scutellum greyish, with the apex very deeply excised. Each elytron with four rather broad blunt costae, which are effaced at the base; the interstices very slightly convex, each with a line of obscure punctures on each side towards the apex. Metanceus conformis. (Plate XVIII. fig. 3.) Lycus (gen. 37) conformis, Waterk., Trans. Ent. Soc., 1878, p. 115. Nigro-fascus, griseo-pubescens; thorace limbo fiavescenti, disco utrinque blimpresso;- elytris sat convexis, sordide fiavis, apico infuscato, costis quatuor obtusis instructis, interstitiis obsolete biseriatim punctatis. Long. 34 lin. Hab. Sarawak (Wallace). Antenmae blackish, with grey pubescence. Thorax fuscous, with the margins dirty yellow;- within each of the four angles there is an ill-defined impression, and in front there are three short Iongitudinal carinwe. Scutellum very deeply triangularly excised, yellowish. Elytra brownish yellow (except at the apex); each elytron has four rather broad blunt costae, which are distinct to the base; the interstices with two rows of obscure subconfiuent punctures. This species is very close to the preceding, but the areolets on the thorax are not well defined, and the costae, of the elytra are distinct to the base. Netanceus fulvus. (Plate XVIII. fig. 2.) Nigro-fuscus, angustus, convexiusculus, pubescens; thorace fulvo, obsolete soptemareolato; elytris parallelis, fulvis, sericeo-pubcscentibus, subtiliter striato-punctatis, interstitiis alternatis convexiusculis. ~.Long. 3-1 lin. Huab. Pcnang (J. C'. Bowring, Esq.). DILOPHOTES. 75 Elongate narrow. Antennae slender, the lamellse springing from the base of the joints long and slender. Thorax fulvous (tinted with grey here and there), straight at the sides, the posterior angles slightly prominent and acute; above with seven ill-defined areolets, the ridges dividing them obtuse. Elytra long, gently convex, each with nine lines of extremely fine elongate punctures arranged in pairs on the back. This species differs from M. dispar in having very slender antennee; from M. conformis in being of a narrower form, in having the thorax narrower with more distinct areolets, the punctures of the lines on the elytra are finer and more elongate, and the alternate interstices are less convex. DILOPHOTES. Thorax rugosely punctured in front, with a smooth mesial anterior carina. Elytra very slightly narrowed towards the apex (where they do not meet at the suture), or parallel, each with three costse, the intervals flat and pubescent. The type of this genus is Lycus (gen. 38) exilis, Waterh.; but I ' have associated with it a second species, which differs in having the elytra parallel. Both these species have the first costa of the elytra abbreviated posteriorly. Celetes pectinifer, Kiesenw. (Berl. ent. Zeit., xviii. 1874, p. 251), from Japan, must, at least for the present, be placed in this genus. In this species the three costse of the elytra are all complete; the male has the antennae pectinate. Dilophotes exilis. (Plate XVIII. fig. 8.) Lycus (gen. 38) exilis, Waterh., Trans. Ent. Soc., 1878, p. 116. Flavescens, pubescens; thorace postice utrinque impresso, angulis posticis acutis; scutello apice truncato; elytris (apice ipso infuscato) pubescentibus, singulis costis tribus; antennis pedibusque infuscatis. Long. 3 lin. Hab. Sarawak (Wallace). Head with a longitudinal impressed line; antenna blackish. Thorax narrowed anteriorly; the surface rugulose in front, with a smooth mesial line, transversely impressed behind, and with a shallow impression on each side.
